Hello everyone! This fanfic is going to be a crossover between Percy Jackson and The Olympians and the manga/anime One Piece. I absolutely adore both, so I decided to write this. However, this story is going to be a PJaTO-centric, and the One Piece part won't come until a bit later. I strongly suggest you read the series AND watch the anime to be able to understand everything. But don't worry if you can't, just enjoy the story. Oh, and since I think this type of crossover hasn't existed yet (as far as I can see), I don't know how many people will be reading this. Maybe it will sit at some dark, dreary, dusty desolate corner in this website. So, if you do, kindly leave a review because this is my first fanfic as well and I want to improve my writing. Thank you!

Disclaimer: I do not own Percy Jackson or One Piece.

Chapter 1

Percy's POV

"…and so, to convert the index form into its logarithm form, you have to…" I tuned out of her yapping, again. I groaned, it was the last day of school before summer, where I would be able to go to camp and meet all my friends again. I missed all of them, especially my loving girlfriend, Annabeth. But now, I'm still stuck at Maths with the most dedicated teacher in Goode High School.

And of course, she didn't like wasting her time, even if this was the last class before dismissal.

"…few laws of logarithm which you have to follow at all times and…" I glanced at the clock which was hung at the corner of the classroom.

Two more minutes.

I groaned again, louder than I meant it to be. Ms Shane suddenly whipped her head in my direction. Uh oh, time to act cool.

"Is there a problem, Mr Jackson?" The class snickered but I regained my composure.

"No, Ms Shane, please continue." I faked my best serious looking face. The class snickered again. She gave me the evil eye before turning back to the class. I swear all my Maths teachers do that to me. Starting from Mrs Dodds, the Fury-in-disguise,

"Okay, if there are no questions, then…" Shit, here comes the "homework-giving" speech. And I was not going to blow any precious summer time solving log questions.

Just then, the dismissal bell rang. Without skipping a beat, all the students raced out of the classroom, with me in the lead. I could faintly hear Ms Shane shouting something about "wait" and "homework". I grinned. Not today, Ms Shane.

After dashing through the corridors and out of the school gates, I slowed down my pace and took in my surroundings as I whistled light-heartedly. The streets of New York City were busy as usual. Cars streamed in from all directions, spewing smoke from the exhaust. I wonder what Grover was going to say about that. Something not meant for children's ears, I'm sure.

I was in a jovial mood, I guess summer holidays does that to everyone. And thinking about Annabeth helped too. I walked up to the front door of my apartment with a broad smile. The summer holidays have started, I'm going to camp tomorrow and best of all, I get to meet my friends again. I opened the door and you could say that I was surprised when I was greeted by two loud "pops" and a spray of confetti in my face.

"Congratulations!" My mum and stepdad greeted me with a smile bigger than mine before.

"Huh, what?" Some people say I'm not the sharpest tool in the shed, Annabeth called me a Seaweed Brain, but some things are just too weird for me to comprehend.

"For surviving another year at Goode without getting expelled! An amazing feat for someone like you, you know?" Paul chuckled. I decided to take it as a compliment.

"Uh, thanks I guess." True. Monster attacks have dwindled down considerably since Kronos' defeat. Any cyclops or hellhounds were dispatched quickly before anyone noticed. Plus, I tried my best this year. Although my grades were still lingering at the average mark, Paul said that it was at least an improvement compared to last time. And I didn't even blow up a single gym locker, not one.

"Well, I guess we better not stop Percy from packing for camp then. You can't wait to see Annabeth again, right dear?" The last question was directed at me, and I blushed a little.

"Yeah, and Grover, the Stoll brothers and maybe Thalia and Nico too if I'm lucky." My sorry attempt went west when my mum said with a smile: "Mm hmm, and are you going to take Annabeth on a date this summer?" I blushed harder at that. After giving them both a quick hug, I speedwalked to my room while rubbing my neck. Chuckles could be heard in the living room.

A familiar view greeted me as I opened my room's door. At the corner of the room was my messily made bed. A small desk stood a little ways of the bed and it was cluttered with books and paper. I threw my bag inside the desk and plopped myself on my bed. I could use a rest before packing, and emptying my mind off the few laws of logarithms.

I stared up at the ceiling and let my thoughts wander on its own accord. Another year had came and went since the battle in Manhattan. Another four seasons had slipped passed quickly, and now it was summer again. But this time, I might actually have a peaceful time. Spending time with my Wise Girl, chasing her around the beach, grabbing her by her waist and spinning her around, with her princess blonde curls flowing around her. Then, I'd stop and whisper in her ear, telling her how much I love her. Staring at her beautiful face and gorgeous stormy gray eyes, we'd lean in closer and… I smiled to myself and fell into a peaceful sleep.

I was awoken by a knock at my door. My mum poked her head in.

"Ah, I see you've fallen asleep, Percy. And you haven't begun packing yet. It's dinnertime already and you better do so afterwards. Come on now. No, don't lie back down. Hurry up!"

I gave an unsightly yawn as I sat back up while rubbing the sleep off my eyes. I was soon revitalized when I set my eyes on the dining table.

Roast chicken and mashed potatoes, with my mum's special brown sauce. And cherry coke. Blue cherry coke, courtesy of some blue food colouring. Just like how she made it when I was little, because I loved the colour, even now.

I suddenly felt like a small kid again. The kid who would want his mum to tuck him in bed before he fell asleep every night. The kid who would be startled by the sound of thunderstorms and would run to his mum and hug her while she whispered words of comfort in his ear. Now, I'm almost seventeen, but sometimes, a small part of me still wanted to be that kid.

I surprised my mum by walking up to her and giving her a bear hug.

"What's that for, honey?" My mum said while smiling.

"Nothing, just that the food makes me feel like a toddler again." I replied.

"Well, to me, no matter how old you are, you'll always be my baby boy." She said while hugging me back tightly.

We separated after a while. Paul, who saw the whole thing, smiled at our little exchange. "Well Percy, you certainly don't want to let your mum's excellent cooking go cold, do you?"

"Hades, no!" I exclaimed and jumped into my chair while attacking my food with vigor. Mum and Paul just laughed at my antics.

After battling my food with a spoon, fork and knife, plus a few covered up burps, I finally sat back with a contented sigh.

"So, how was it?" My mum asked.

"Are you kidding, mum? It's absolutely delicious! Even after all these years, your cooking is still the best! Better than the camp's barbecue even." I said.

"Yeah, if I get to come home to a meal like this prepared by my wife every day, I'd feel like the luckiest man on Earth." Paul agreed.

"Uh uh" I said. "That would be me."

"Now, now, that's enough my two fine gentlemen." My mum laughed. "Percy, you will have to pack now if you want to leave early tomorrow."

I sighed. "Sure mum, I'll go now."

I entered my room and walked to my closet. I rummaged through my clothes until I found a couple of casual looking T-shirts and shorts, and let's not forget some clean underwear. I didn't have to pack a lot, since the nymphs do the laundry in camp.

After packing, I began to feel tired and yawned again, despite my sleep not too long ago. To make tomorrow come quicker, I decided to surrender to my fatigue and climbed into bed. Tomorrow, the fun would finally start.

Summer holidays, Camp Half Blood and Annabeth , here I come.
